A pharmaceutical company wants to transport its one pharmaceutical product from a number of sources to a number of destinations. The availability of the product at each of the sources and demand at each of the destinations along with cost per unit of transportation (in $) from each of the sources to each of the destinations are shown in a table below. To From N J K Availability G 7 4 5 500 M 5 4 3 600 T 8 9 6 400 Demand 600 300 600 i. Find the initial feasible solution along with the total transportation cost by the North-West corner rule. ii. Using the initial feasible solution found by North-West Corner rule, find how many units should be transported from each source to each destination to minimize the total transportation cost by the Stepping-stone method. iii. Find the minimum total transportation cost of the solution found in ii. iv. Find the initial feasible solution along with the total transportation cost by the Vogels Approximation Method. v. Check whether the solution found in iv. is the same as the found in
